SPECIFICATION formingpart of Letters Patent No. 746,730,dated December'15, 1903. Application nea my 2a,19os.1 sean No. 167.293. mo man;

To LZ whom il? may concern,.-

Be it known that I, SAMUEL MORRIS, a citizen of the United States,residing at Newark, in the county of Licking and State of Ohio,

`5 have invented certain ne'wvand useful Improvementsin Car-Couplings;and I do hercby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it io appertains to make and use the same.

The object of this invention is to provide a carwcoupling of simple andimproved construction in which the coupling may be automatic, and whichmay be quickly and easily manipulated to prepare for uncoupling.

zo a horizontal sectional view of the draw bar and head, showing theknuckle and knucklelocking parts in plan and in locked position.

Fig. 2 shows the same sort of vieW,'eXcept that the knuckle andknuckle-locking parts are in uncoupled position. .Fig.'3 is a verticalsectional-view taken on the plane a; as,`

Fig'. l, looking in the direction indicated by the arrow, theknuckle-lock being in lockedv Fig. 4 is a similar view to that ofVposition.

that the lock is shown to be raised. Fig. 5 is a perspective view of theknuckle.

Like characters of reference rin the several views designatecorresponding parts.

l designates the draw-bar, and 2 the knuckle. The knuckleis pivoted on`a pin 2f in the draw-head, as usual. The knuckle has the usual outercoupling portion or jaw and an inner arm 2ad with a beveled upper side2b,

4o adapted to pass under the knuckle-lock, as

hereinafter described, a dat-ended lock-en-`l gaging toe 2,andahook-shaped heel 2d. The draw-head has an appropriate cavity tocontain the knuckle-lock and knuckle-lock-oper- The cavity also has aninward projection liL back of the pivot 2f to be engaged by the heel 2don the knuckle-arm 2a when the cars are coupled.

3 designates the dog or lock for locking the This is pivoted at 3a inthe rear of the cavity of the draw-head, so as to beV capable ofoscillating in a vertical plane or at right angles to and intersectingthe plane in which the arm 2a of the knuckle oscillates. The rearportion of the knuckle-lock is formed into an angularly-projecting toe3, having its upper edge beveled toward the lever fl, as indicated at3C. l

4 designates the lock operating device. This consists of a smallhorizontally-swinging lever having for its fulcrurn a vertically-lstanding cran k-shaft ai, the upper or cranked end of which is above thetop of the drawhead. The shaft 4a can be rocked by means of a rod (notshown) extending to the side of the carer by any other appropriatedevice accessible to the trainman.

When the cars are coupled, the parts stand approximately as seen in Fig.l. When it is desired that the cars be uncoupled, the lever 4 is turnedso that the inner arm thereof strikes the toe 3b and lifts the dog, asseen in Fig. 4, after which the arm 2a is free to move outward. When thea`rm 2ab is turned out by the action of the outer end of the lever 4 onthe leg 2a, thel dog is supported on the inclined surface 2b, andbecause this inclined surface 2b tends upwardV the dog is lifted and theangularlyprojecting toe 3* depressed, thus permitting the inner arm ofthe lever to be turned outward to lie Within the angular space betweenthe dog 3 and toe 3b, as seen in Fig. 3, and therefore in position tolift the dog when it is again desired to uncouple coupled cars,

f When the coupling is to be set to open position preparatory tocoupling, as seen in Fig. 2, the Vouter arm of the lever l can be turnedtobearnpon or .strike the inner side of the arm 2=ito move said arm asfar outward as the circumstances may require.

` The .inclined or beveled portion 3c of the toe 3b permits the leverltto ride over the toe into the angular space between the toe and the dogshould it happen that the dog is left low down on the incline 2b.

The invention'is susceptible of' modifica tion. For example, instead ofresting on the inclined portion 2b in the opening position4 of thecoupling the dog 3 can be held up by the lever 4.

- If the pin 2f should be lost or cut off by an ICO extraordinary load,the cars will still remain coupled because of the engagement of the heel2d with the projection la.

What I claim, and desire to secure by Letters Patent, is-

l. In a car-coupling, the combination of the knuckle having ahorizontally-swinging arm with a lockinglend thereon, averticallyrocking lever or dog adapted to engage the locking end of theknuckle-arm and having an angularly-projecting toe 3b, a horizontalrocking lever unattached to said dog, adapted to act on said toe tooperate it and pass over the same 1 2. In a car-coupling, thecombination of the knuckle having a horizontally-swinging SAMUEL MORRIS.
